Description Ed Page 2011-07-07 03:59:06 EEST

Created attachment 371 [details]
Example script for both PyQt4 and PySide

(sorry if fixed already, PPA has not been updated)

The attached script has two main variables to tweak: PYSIDE and
DISCONNECT_ON_DELETE.

Expected behavior:
PYSIDE = False # Runs PyQt4 version
DISCONNECT_ON_DELETE = False
Result? slot is disconnected automatically and never executed

Actual behavior:
PYSIDE = True
DISCONNECT_ON_DELETE = False
Result? slot is executed, causing exceptions to be propagated through my code
and depending on root cause, very subtle behavioral changes

"DISCONNECT_ON_DELETE = True" is to demonstrate the work around I am having to
implement in my code.  This is messy because it is hard to determine if I hit
every code path.  I also worry that if the root cause deals with keeping
references around then I could have some subtle bugs.
